* Make the plasmoid resize automatically with the text of the label
  label. I think this is a bug in Qt 4.4 that will be fixed by Qt 4.5.
* Support for ANSI escape secuences for colored output :-) [horchi]
* Set a label as a headline above the output. [buschmann23]
* FIX: When you change filtering settings the plasmoid would have to
  reload the data so it can process it again. Possible fix: Avoid not
  reloading the data :P
* Scrollbars.

IDEAS:
* Let the user choose the environment variables with a dialog? Maybe that's
  too much hassle for nothing, after all it's just matter of executing a
  command like: "MYVAR=myvalue program --arguments"
* Let the user choose the current working directory? the same as before.
* What about capturing the standard input? I won't be making a terminal
  emulator, but something really easy... to let the user interact with
  the application... I think it's not worth it.
* Add a sort function? for commands it's not necessary... you just do
  "mycommand | sort", but for files could be usefull maybe?
* Let the user choose an icon for every and each instance of the applet, so
  he/she can distinguish when in the panel amongst other instances of the
  plasmoid.
* Plasma::Applet::addAssociatedWidget(); ??? Shortcuts?? What is this?
